Decided to re-center the valve in the H block to get the brake warning light to turn off. Pretty easy until the time came to pull the valve and clean out the block - FROZEN! Anyway, after PB blasting and tugging several times, decided to get it out the hydraulic way. Plugged four of the side holes with brass plugs and the remaining passenger side hole with a male/female fitting. Unscrewed the tip off the grease gun and threaded it into the m/f fitting. One pump on the gun and the valve came right out. Thought this might be useful to someone trying to do the same. Beats buying a new/used block!
